<b> Calvin: </b> "I take nouns and adjectives and use them as verbs. Remember when `access' was a thing? Now it's something you <i> do </i>. It got verbed." <br>
<b> Calvin: </b> "Verbing weirds language." <br>

<h2> Current Research Projects </h2>

<dt> <h3> <!WA0><a href="http://www.cs.utah.edu/projects/nlp/sundance.html"><!WA1><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Information Extraction </a> </h3>
<dd> Our natural language processing research focuses on
<i> information extraction </i>, which involves recognizing and
extracting specific types of information from text. We are currently
building a new conceptual sentence analyzer called Sundance (Sentence
UNDerstanding ANd Concept Extraction).   

<dt> <h3> <!WA2><a href="http://www.cs.utah.edu/projects/nlp/autoslog.html"><!WA3><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Automated Dictionary Construction </a> </h3>
<dd> We have developed the AutoSlog dictionary construction system
that generates dictionaries of extraction patterns automatically using
an annotated corpus. We are currently working with a new version,
AutoSlog-TS, that does <i> not </i> require text annotations but
simply preclassified texts instead.  
  
<dt> <h3> <!WA4><a href="http://www.cs.utah.edu/projects/nlp/signatures.html"><!WA5><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Text Categorization </a> </h3>
<dd> Our approach to text classification an underlying information
extraction system to recognize linguisic context in order to achieve
high precision. We have developed several algorithms for
text classification, including the relevancy signatures algorithm, the
augmented relevency signatures algorithm, and a case-based
classification algorithm. 

<dt> <h3> <!WA6><a href="http://www.cs.utah.edu/projects/ursa"><!WA7><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Information Retrieval </a> </h3>
<dd> The URSA (Utah Retrieval System Architecture) Project has been
ongoing at Utah for many years and involves building query-based retrieval
engines and text browsers.
